Question

Proteins with greater charge density move faster in the PAGE.

(a) True

(b) False

I had been asked this question in an internship interview.

Asked question is from Techniques in section Techniques in Cell Biology of Cell Biology

Answer 1

The correct answer is (a) True

For explanation I would say: Charge density is the charge per unit mass of the protein molecule. The rate of movement of a protein through the gel matrix depends on its charge density, the more the charge density, the faster the protein will reach the electrode.
